This seems related to the 3g hotplug code.

Do you happen to know the exact brand and/or type of parallel-to-usb unit used?

As part of the upcoming 2.3.7.0 firmware release, we're reviewing old open tickets to see if they are still relevant, which is why you get this response now.

If this issue still occurs with the 2.3.7.0 rc2 firmware, feel free to leave a comment here so we can further investigate.
